1 Anti-Mycotoxin Additives

2 EFFICACY OF MYCOAD AGAINST AFLATOXIN IN LAYERS EXPERIMENTAL PROTOCOL Caged ISA Brown layers already in production were transferred from a commercial farm to an experimental unit at Samitec in Santa María, RS, Brazil. A seven-day adaptation period to the new facilities was allowed before starting the trial at 40 weeks of age. Birds were distributed using a complete randomized design into 3 treatments with 4 replicates of 10 layers each kept in communitarian cages (1.40 m²/cage) with slatted floor, equipped with semi-automatic feeders and automatic nipple drinkers. The building was maintained at an environmental temperature of 20 C ± 1 C and all laying hens were kept under uniform management conditions. All ingredients were tested free of mycotoxins contamination. The aflatoxin (AFL) used for the contaminated diets was produced in LAMIC (Lab. of Mycotoxicological Analysis). At the beginning of the trial feed consumption was kept at 120 g/bird and later increased based on egg production, following the genetic management guide. Water was supplied ad libitum and the experimental diets fed for 41 days. Performance parameters and egg characteristics were evaluated weekly. The relative weight of the liver was evaluated at the end of the trial AFL 3. AFL+MYCOAD Aflatoxin MYCOAD * 0.25 * 0.25 = 2.5 kg MYCOAD/MT RESULTS Performance, egg quality and relative liver weight after 41 days of treatment Production Mass kg Weight g Feed Conversion kg/kg Meat and blood spots Liver Weight Mortality a 1.88 a 61.3 a 2.61 a 0.60 c 2.31 c 0 AFL b 1.28 b 59.8 c 3.76 b 0.75 a 2.97 a 5.0 AFL 0.25 MYCOAD a 1.80 a 60.5 b 2.70 a 0.69 b 2.67 b 2.5 a, b, c Values within each column with different letters are significantly different (P< 0.05)

MYCOAD demonstrated its efficacy in preventing the toxic effects caused by aflatoxin in laying hens.

5 EFFICACY OF MYCOAD + MYCOAD AZ AGAINST AFLATOXIN + FUMONISIN + T-2 TOXIN IN LAYERS EXPERIMENTAL PROTOCOL Exactly the same protocol described in the previous trial was used in this experiment. MYCOAD and MYCOAD AZ were both added to the feed as anti-mycotoxin additives. A combination of mycotoxins, including aflatoxin, fumonisin (FUM) and T-2 toxin (T-2) were simultaneously added to the contaminated diets. All mycotoxins were produced by LAMIC.

AFL+FUM+T-2 MYCOAD+MYCOAD AZ 10 ppm 1 ppm * * 0.25 = 2.5 kg MYCOAD/MT 0.10 = 1.0 kg MYCOAD AZ/MT RESULTS Performance, egg quality and relative liver weight after 41 days of treatment Production Mass kg Weight g Meat and Blood spots Feed Conversion kg/kg Liver Weight Mortality AFL 10 ppm FUM 1 ppm T-2 AFL+FUM+T-2 MYCOAD 0.25 MYCOAD AZ a 1.88 a 61.3 a 0.60 c 2.61 a 2.31 c c 1.17 c 60.2 b 0.79 a 3.87 c 3.25 a b 1.54 b 59.8 b 0.68 b 3.01 b 2.90 b 2.5 a, b, c Values within each column with different letters are significantly different (P< 0.05)

MYCOAD AZ combined with MYCOAD, demonstrated its efficacy in preventing the toxic effects caused by the combination of aflatoxin + fumonisin + T-2 toxin in laying hens. Reference. Mallmann, C. A., D.
